Ouch - Stopped Out!

So far it looks like I predicted the direction of the market correctly yesterday. Had a meeting from 9-11 this morning and I set a stop. The stop was set at NQ (December) = 1808 which was the point where the stochastic would rise above 80 and negate the sell signal from the day before. The stop was hit and then the market dived. Lost $140 on the trade - guess it could be worse. But even when I'm right I am losing money which is discouraging. I'll wait for a bounce and re-evaluate whether to go short again.
